The Travel Channel has postponed Man Finds Food – slated to premiere Wednesday – after the show's star exploded at Instagram followers over a controversial hashtag.

Adam Richman, 40, hosts many of the network's successful programs, including Man vs. Food and Best Thing I Ever Ate. But the TV personality caused a social media stir last week when he captioned an Instagram selfie "#thinspiration," a term used on websites promoting anorexia and bulimia.

When activists pointed out the word's dangerous meaning, Richman lashed out, according to screenshots captured by blogger Amber Sarah.

"Seriously grab a razor blade & draw a bath. I doubt anyone will miss you," he reportedly wrote in the exchange.

"I've long struggled with my body image and have worked very hard to achieve a healthy weight," he said in the statement. "I'm incredibly sorry to everyone I've hurt."

The foodie recently celebrated his 70-lb. weight loss by posing naked for Cosmopolitan U.K.'s July issue. And in December, he penned a piece for Men's Health about his weight loss, writing: "I went in for a checkup, and when my doctor had me stand on a scale, even he was surprised. Seeing that number (which I'll take to the grave) was a turning point. I knew I needed to make a change."
